$PEOIFIGATION forming part of Letters Patent No. 705,404, dated July 22, 1902. Application filed May 24, 1901. Serial No. 61,749. (No model.)

To CLZZ whom, it may concern.-

Be it known that we, CHARLES M. HOPKINS, residing at Union City, in the county of Erie, and EDWARD H. DORN, residing at Spartansburg, in the county of Crawford, State of Pennsylvania, citizens of the United States, have invented a new and useful Milk-Can, of which the following is a specification.

This invention relates to milk-cans in general, and more particularly to that class employed for shipping and storing milk, the object of the invention being to provide a con struction in which the milk-holding portion will have aprotective casing so disposed as to permit a circulation of air between it and the holding portion, a further object of the invention being to so form and attach the bottom of the milk-holding portion as to permit ready cleaning of the can.

Further objects and advantages of the invention will appear from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a vertical central section of a milk-can embodying the present invention. Fig. 2 is a bottom plan view of the cover of the can. 1

Referring now to the drawings, the can comprises a body or milk-holdin g portion 5,which is substantially cylindrical in form and the inner surface of which is free from all rivets and other projections upon which solid matter is liable to lodge, the bottom of the body being concave on its inner side, as shown, so that the angle between the bottom and side of the body is sufficiently large to permit ready cleansing. The upper end of the body portion 5 is flanged outwardly, as shown, and this flange 6 rests upon an inwardly-projecting annular flange upon the inner face of the v casing 70f the can, this casing being extended upwardly above the flange 8 thereof to form the upper end of the milk-holding portion of the can, the connection between thetwo flanges being soldered to prevent leakage. The casing 7 is cylindrical in form and extends to a point below the bottom of the body 5, the lower end thereof being open and beaded to form a support for the can.

In the lower end of the casing 7 and below the body 5 is disposed a strengthening-web 10,which is disk-shaped and is dished, so that its central portion at its convex side will lie against the outer surface of the bottom of the body, against which it is secured by solder. The outer edge of the web 10 lies in a plane below the central portion thereof and is attached to the inner surface of the casing 7 by solder or in any other suitable manner. As an additional strengthening means,V-shaped plates 12 are disposed between the web 10 and the bottom of the body 5, the sides of the plates being curved to conform to the curvatures of the bottom and the web, the ends of the plates being bent laterally and riveted to the inner face of the casing. The plates 12 are thus wedged into place and not only prevent lateral movement-of the lower end of the body within the casing, but assist in supporting the body, as will be seen.

To permit a free circulation of air between the body 5 and the casing 7, perforations 13 are formed in the casing just below the flange 8, while additional perforations 14 are formed in the casing below the web 10, said web having also perforations 15, so that air-currents may pass into the space-between the body and the casing, the draft being through perforations 14 into the space below the web 10, thence through perforations 15, and then up wardly between the body 5 and the casing 7, and finally outwardly through the perforations 13, so that the casing is well ventilated.

The closure for the can consists of a frustoconical portion 16, adjacent the outer edges of which and at the concave side is secured an annular flange 17 of such diameter as to fit snugly within the upper end of the casing, where it projects above the body 5 and forms a portion of the can proper, and upon the inner face of this flange and at the inner end thereof are formed or secured two lugs 18 and 19, which act to hold rotatably a disk 20 between them and the top portion 16 of the cover. This disk 20 has a recess 21 at one edge, which receives the lug 18 during the application and removal of the disk. In applying the disk its edge is engaged under the lug 19, and it is manipulated to cause the lug 18 to pass through the recess or notch, after which the disk is given a partial rotation to prevent it from dropping from place. hen the disk is to be removed, the notch is brought to register with the lug, and the notched edge of the disk is first drawn outwardly, after which its opposite edge may be drawn from under lug 19. To facilitate this manipulation of the disk, a bowed handle 22 of common form is soldered to the under side thereof. The disk 20 has a central annular opening 23, having a screen-closure 24, while a second annular opening 25 is formed in the top 16 of the closure and directly above the opening 23, the openings 23 and 25 beingin axial alinement, the opening 25 having also a screenclosure 27. A cylindrical extension 28 of the top 16 surrounds the opening 25 and is adapted to receive the flange 29 upon the under side of a top plate 30, which closes its upper end, the top plate having a handle 31, as shown. Perforations 32 and 33 are formed in the extension 28 and flange 29, respectively, and which perforations are adapted for alinement at times when the top plate is rotated, so that air maybe admitted to the interior of the can when desired, the screen-closures of the openings 23 and 25 preventing access of foreign matter.

Handles 34 are pivoted to opposite points upon the casing 7 to facilitate moving of the can.

With this construction it will be seen that the body 5 is protected from dents during shipment, the can may be well ventilated, and the body portion is free from all formations that tend to retain solid matter and make cleaning of the can laborious.

It .will be understood that in practice various modifications of the construction shown may be made and that any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

\Vhat is claimed is-- 1. A milk-can comprising a body portion having an outwardly-extending flange at its upper end, a casing inclosing the body portion and extending thereabove, an internal flange upon the casing upon which the flange of the body rests, and a closure for the body engaged with the casing.

2. A milk-can comprising a body portion having an outwardly-extending flange at its upper end, a casing inclosing the body portion and extending thereabove, and separated from the body at its sides to form an interspace,said casing having an in ward ly-directed projection upon which the flange of the body rests, and a closure for the body engaged with the upper end of the casing.
